Degree positions qin frame 30 and backboard 20.
However, having the case where separating panel 10 and backboard 20 from qin frame 30 in the repairing of violin 1.Pin is made
For positioning, the fixation of qin frame 30 and panel 10 and the fixation of qin frame 30 and backboard 20 are not facilitated.However, by qin frame 30
In the process bonded with panel 10 and the process for bonding qin frame 30 and backboard 20, there is adhesive to flow into the first hole or second
The case where hole.In this case, if pin is fixed with backboard 20 using adhesive with qin frame 30, pin with panel 10 or pin,
Panel 10 is separated from qin frame 30 and backboard 20 is more bothersome.It is therefore preferable that bonding force, pin and face between pin and qin frame 30
Bonding force between bonding force and pin between plate 10 and backboard 20 is weaker, though so as to adhesive flow into pin with qin frame 30 it
Between, also panel 10 and backboard 20 easily can be separated from qin frame 30.
In the present embodiment, the material of qin frame 30, panel 10 and backboard 20 is timber.In addition, pin material not by
It is particularly limited to, but it is preferred that resin or metal.In the case where the material of pin is resin or metal, according to carpenter institute
The adhesive used, even if then adhesive flows into the first hole or the second hole, also due to panel 10, backboard 20 and qin frame 30 with
Bonding force between pin is weaker to be become easy so repairing.As such adhesive, glue or vinyl acetate resin latex
Relatively it is suitble to.In addition, the material of pin is to select for the viewpoint for considering the bonding force repaired, therefore the surface of pin is resin
Or just it is enough for metal.That is, also can use resin coating timber, the timber of the metal covering cylinder of cylinder also can use.
In general, about the panel of violin and backboard, compared with central portion, the thinner thickness of peripheral part.This is
For the sake of increasing the vibration of panel and backboard.The vibration of violin is classified into various modes, but with panel and backboard
The vibration in vertical direction occupies biggish ratio in the vibration entirety of violin.It in the present embodiment, can as pin
Use the material different from timber.Alternatively, in the case where the material of pin is timber, be also able to use with panel 10, backboard 20,
And the different types of timber of qin frame 30.Pin is set between panel 10 and backboard 20 and qin frame 30, therefore can be according to pin
At least one of the diameter of material, the length of pin and pin adjusts longitudinal vibration.For example, if the material as pin uses
Rubber then than timber softness, therefore can be such that panel 10 more easily vibrates in vertical direction.That is, by reducing panel 10
The rigidity of peripheral part can improve the rising of sound.
In this way, pin not only has the function of used in the positioning of qin frame 30 and panel 10 and backboard 20, it may have adjustment is small
The function of the tone color of violin 1.As a result, and without using pin by the previous violin phase of qin frame and the fixation of panel and backboard
